Simplifying quality control and standardization of CTD data under SeaDataNet requirements

Sharing marine data through SeaDataNet infrastructure ensures preservation and promotes reusability. Submission of data to this infrastructure demands a set of technical tasks that cover quality control processing, adoption of common vocabularies, implement fle format standards and preparation of associated metadata. Although common software tools are made available to Data Centres and/or End Users to facilitate data and metadata preparation, these tasks continuous to be complex and time-consuming. To speed-up this process, a Python-Flask web application is presented here to quality check and create metadata and data according to SeaDataNet requirements. The web tool focuses on CTD vertical profles, although code could be easily adapted to process other type of records.Peer Reviewe

An all-in-one web tool to apply CTD quality control, format data, and generate metadata under SeaDataNet criteria

Professional data centres of the Pan-European region active in marine data collection, in particular National Oceanographic Data Centres (NODCs), routinely share diverse datasets through SeaDataNet, a distributed Marine Data Infrastructure. This network provides on-line integrated databases of standardized quality. Sharing marine data through SeaDataNet is an optimal way of ensuring FAIR principles: Findable, Accessible, Interoperable and Reusable. However, submission of data to this infrastructure demands a set of technical tasks that cover quality control processing, adoption of common vocabularies, implement file format standards and preparation of associated metadata. Although common software tools are made available to NODCs to facilitate data and metadata preparation (see https://www.seadatanet.org/Software) these tasks continuous to be complex and time-consuming. For example, the technician must use MIKADO software to generate INSPIRE-complaint metadata and adopt SeaDataNet Common Vocabularies; NEMO software to transform the original file to a common data transport format; and OCTOPUS software to check the compliance of a file. Additional software must be used to quality check and properly flag each individual record.En prens

Nivel del mar en las costas españolas y su relación con el clima

Ponencia presentada en: III Congreso de la Asociación Española de Climatología “El agua y el clima”, celebrado en Palma de Mallorca del 16 al 19 de junio de 2002.[ES]La series del nivel del mar procedentes de la red de estaciones mareográficas costeras operadas por el IEO pueden ser consideradas por su longitud y su distribución geográfica un índice de la variabilidad regional climática. El análisis de conglomerados jerárquicos presenta 3 regiones diferenciadas en las que, mediante el ACP, se han encontrado tendencias regionales que varían desde 2.4 mm/año en el norte de la península ibérica (región de transición), 0.9 mm/año en el estrecho y 0.8 mm/año en Canarias (región subtropical). La variabilidad decadal no permite encontrar valores de aceleración fiables para la longitud de estas series. Las correlaciones encontradas con las presiones en costa son altas y algo inferiores con el índice de la NAO lo que permite deducir que las variaciones del nivel del mar registrado en costa, aparte de las señales locales, mantienen las características propias de la región.[EN]The coastal sea level time series operated by the IEO tide gauge network can be considered, in attention to its length and geographical distribution an appropriated regional climatic variability index. A PCA performed to the 3 difference regions founded by a clusters analysis, gives regional trends from 2.4 mm/year on the north of the Iberian peninsula to 0.9 mm/yr in the Strait of Gibraltar and 0.8 mm/yr in the Canary islands. The decadal variability gives no evidence to reliable acceleration values. The correlation between mean sea level is higher for atmospheric pressure than for the NAO index. It shows that the variation in coastal sea level keeps the local signals in addition to the regional behaviour
